Closing this Forum to non-members
Since the last non-member post to this Forum was over a month and a half ago, with the permission of Bill Patterson, and due to the increase in spam, I am closing this Forum to non-members (Guests). It remains open for members.
If any non-member wishes to add to this discussion, you are welcome and urged to become a member.
Thanks everyone who has contributed here and I hope that you will continue to do so.
